MROVED CRA'CKER-MACEINE,

'.ll'lel Schedule referred/to in these Letters Patent and making part of(he same.

vented certain 'new and useful. Improvements inVMachines for lCuttingout Crackers, &c.;'and lido-hereby declare that the following is a full,clear, and exact description thereof,reference being had to the accompafnying drawings, making part of'this specification, and to the letters ofreference. marked thereon, like letters indicating like parts whereverthey occur.

To enable others skilled in the art to construct and use my invention, Iwill proceed to describe it.

f My invention relates to machines for cutting crackers andcakes fromdough and It consists in providing a'hollow cylinder with a set ofcutting and pcrforating-devices, andv also with perforations throughwhich the surplus dough is forced into the interior of said cylinder,from'whence it is removed by al screw; and in .arranging a series pfcords,

to-remove` the crackers` from the dies when cnt; all as i hereinafterexplained. y

Figure 1 chine;. f l e M Figure 2 is aftransverse vertical section; andlongitudinal vertical section of the is a perspectiveyiew of my improvedmasame. y

To construct my machine, I` provide a suitable frame, D, `and mountthereon a hollow metallic cylinder, G, having arranged on itsexterior'surface a series of cutters, or dies, of the size and form thatthe cakes or p crackers are intended to be,these cutters consisting ofprojecting rims, or flanges, K, placed as close toi gether as they canbe, as represented in iig. l.

A series of pins, R, is arranged within each of 4the circles, orcutters, for perforatin g, or pricking the crack- `ers;, and there arerecessesformed in the cntters,lin s'uch a manner as to pass around thecylinder C, for

the reception of a small wire or cord, H, said wires or cords alsopassing around a roller, F, located below and in front of said cylinderC, as shown in g. 1. f

Perforations, c, are made `through theshell ofthe `cylinder-C, of `asizeand form` corresponding with the spaces between the cutters, wherethe latter'come as .near'together as their form will admit, asrepresented in iigs. 1 and 2, 'for the waste, or surplus `dough to passthrough, intothe interior of the cylinder; and inside of the cylinder Ois located a spiral-winged scraper, or screw, G, which serves toremoyethis surplus dough, and force it out at one end of the sented in figs. 1and 3.` i

The journals b, of the screw, pass through,`aud have theirbearings inthehollow journals a, `of the cylinder cylinder, as repre- C, andset-screws,c, are arranged for adjusting the cylinder O, and keepingitin contact with the surface Vof' another cylinder, E, placed'underneath the cuttingcylinderO, and against which the latter bears, asshown `in ligs. land 3.

A hopper, or incline, L, is arranged in rear oi' theV cylinderO',forreceiving the dough, and feeding it to the cylinder and in front 'isplaced another slide, or

incline, S, to receive the sheet of' crackers as it passes from betweenthe cylinders, `and convey it to an endless apron, A, passing aroundrollers suitably located, as represented in fig. 2, these latter`devices being in common use in similar machines, and, therefore,forming no part of my present invention.

The operation is as follows:

The machine being set in motion, asheet of dough is placed on theinclineL, and fedv into the machine. As it passes through between thecylinders, it is cut into proper form by the cutters K, the pinsA Rprickin g,or perforating the crackers at the same time, the

surplus dough between the cutters being forced through the openings einto the interioroi the cylinder O, from whence it is removed by thescrew G, which may be nnade to revolve in an opposite direction from thecylinder.

- rlhe crackersare held together by the small uncut portions in therecesses in the cutters, and asthe cylinder revolves, the sheet ofcrackers is lifted out of the cutters by the cords H, which lie in saidrecesses, nn-

der the sheet of dough.

By this means, I make a machine that operates with ythrough 'the shellof the cylinder, in the spaces between the cutters,/ to permit thesurplus dougli'to pass through intothe `interior of the cylinder,substantially as described". i

2. The screw G, located within said cylinder C, and

arranged to operate in connection therewith, substantially as and forthe purpose 'set forth.

3. The combination, with cutting-cylinder C, of the wires or-cords H,when arranged to operate as described, for the purpose of removing the'crackers from the cutters, as set forth. Y
